Overview

ℹ️

VDBH 217 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature.

Relatively close High extinction Near-solar metallicity Young

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.

Cavallo et al. (2024)
Gold sample.
